Why do people forget that Biden told everyone he would be a one term/transitional President during his campaign. If theres a moment, then its the moment Joe Biden decided to go against his own pre-Presidential calculations and try to hold onto power for a second term.
Justifications aside, he should have allowed the democratic process to follow through naturally (as much as is possible in that byzantine system). And fully supported the Democratic party's choice as an elder Statesman and soon to be Presidential Alumni who qould be remembered for his commitment to democracy over power, rather than power over democracy.
